Alkali Scientific EDTA 0.5M Solution pH 8.0, 250 Milliliters
EDTA (Ethylenediaminetetraacetic Acid) 0.5M solution at pH 8.0 is a widely used chelating agent in molecular biology and chemistry for binding metal ions that could otherwise interfere with biochemical reactions. This 250mL solution is ideal for larger-scale laboratory applications, such as DNA extraction, protein purification, and enzymatic assays, where metal ion inhibition is crucial. EDTA works by sequestering metal ions like magnesium and calcium, which are essential cofactors for many enzymes, thereby preventing unwanted enzymatic activity. This reagent is commonly used in molecular cloning, gel electrophoresis, and sample preparation for analysis, ensuring consistent results in nucleic acid and protein-related studies.
